Frequently Asked Questions

Does white noise actually help you sleep?

Research supports white noise for sleep in noisy environments. White noise masks disruptive sounds (traffic, snoring, neighbors) by providing consistent background noise. For people in quiet environments, the benefit is less clear. Most studies show improvement in sleep onset time and fewer awakenings in noisy settings.

What is the difference between white noise, pink noise, and brown noise?

White noise contains all frequencies equally — sounds like static or hissing. Pink noise is weighted toward lower frequencies — sounds like rainfall or wind. Brown noise is even more weighted toward low frequencies — sounds like heavy rain, thunder, or ocean surf. Many people find brown noise more pleasant for sleep than white noise's sharper quality.

Can I play sleep sounds all night without draining my battery?

Enable sleep timer so sounds stop after you've fallen asleep (typically 30-60 minutes). Set the screen to lock/off while playing. Most apps support background audio. At minimum brightness and screen off, battery drain from audio playback is minimal.
